Ingredients
This recipe makes 4 servings.
-
For the Soup Base
- 4 cups (960ml) full-fat coconut milk (about two 13.5 oz cans)
- 2 cups (480ml) chicken broth (or vegetable broth for vegetarian option)
- 1-inch piece fresh galangal, thinly sliced (about 6-8 slices)
- 2 stalks lemongrass, tough outer layers removed, bruised and cut into 2-inch pieces
- 4-5 kaffir lime leaves, torn or crushed to release aroma
- 1-2 fresh bird’s eye chilies, thinly sliced (adjust to your spice preference)
- 8 oz boneless, skinless chicken breast or thighs, thinly sliced against the grain
- 1 cup sliced straw mushrooms or oyster mushrooms
-
For Flavor and Garnish
- 3 tablespoons fresh lime juice (from about 2 limes)
- 2-3 tablespoons fish sauce (adjust to taste)
- 1-2 teaspoons granulated sugar (to balance flavors)
- 1/4 cup fresh cilantro, chopped, for garnish
- 1/4 cup green onions, sliced, for garnish
Step-by-Step Instructions
-
Step 1: Prepare the Aromatics
Start by preparing your aromatic ingredients. Thinly slice the galangal. Remove the tough outer layers of the lemongrass, then bruise the stalks with the back of a knife or a rolling pin to release their oils, and cut them into 2-inch pieces. Tear or crush the kaffir lime leaves. Slice your bird’s eye chilies.
Small tip: Bruising lemongrass and tearing kaffir lime leaves helps to infuse maximum flavor into your soup.
-
Step 2: Slice the Chicken and Mushrooms
Slice the chicken breast or thighs thinly, against the grain. This makes the chicken tender and ensures it cooks quickly. If using, slice your mushrooms into bite-sized pieces.
Small tip: Slicing chicken thinly helps it cook evenly and absorb the soup’s flavors better.
-
Step 3: Simmer the Coconut Milk and Broth
In a large pot or Dutch oven, combine the coconut milk and chicken broth. Bring the mixture to a gentle simmer over medium heat. Do not let it come to a rolling boil, as this can cause the coconut milk to separate.
Small tip: Maintaining a gentle simmer is key to a smooth, creamy coconut milk base.
-
Step 4: Infuse with Aromatics
Add the sliced galangal, bruised lemongrass, torn kaffir lime leaves, and sliced bird’s eye chilies to the simmering coconut milk mixture. Let it simmer gently for about 8-10 minutes. This allows the wonderful fragrances to fully infuse the broth.
Small tip: The longer these aromatics simmer, the deeper and more complex the flavor of your soup will be.
-
Step 5: Cook the Chicken and Mushrooms
Add the thinly sliced chicken and mushrooms to the pot. Continue to simmer gently for about 5-7 minutes, or until the chicken is cooked through and the mushrooms are tender. Avoid overcooking the chicken, as it can become tough.
Small tip: Chicken cooks quickly in hot broth, so keep an eye on it to prevent overcooking.
-
Step 6: Season the Soup
Remove the pot from the heat. Stir in the fresh lime juice, fish sauce, and granulated sugar. Taste the soup and adjust the seasonings as needed. You are looking for a balance of sour, salty, sweet, and a hint of spice.
Small tip: Always taste and adjust seasonings at the end. Different brands of fish sauce or limes can vary in intensity.
-
Step 7: Garnish and Serve
Ladle the hot Tom Kha Gai into serving bowls. Garnish generously with fresh chopped cilantro and sliced green onions. Serve immediately and enjoy the incredible flavors!
Small tip: You can remove the galangal, lemongrass, and kaffir lime leaves before serving if you prefer, as they are not typically eaten.
Tips & Variations
- Gluten-Free Option: This recipe is naturally gluten-free! Just ensure your fish sauce is certified gluten-free, as some brands may contain wheat.
- Vegan/Vegetarian Option: Easily make this soup vegan or vegetarian by substituting chicken broth with vegetable broth. Replace the chicken with firm tofu (pressed and cubed) or add extra mushrooms like shiitake or oyster mushrooms. Use a vegan fish sauce alternative or a dash of soy sauce and extra salt to taste.
- More Vegetables or Protein: Feel free to add other quick-cooking vegetables such as thinly sliced bell peppers, snow peas, or baby corn during Step 5. Shrimp or firm white fish fillets can also be added instead of or in addition to chicken; they cook very quickly.
- Spicy Version: For those who love heat, add more bird’s eye chilies. You can also crush a few chilies and add them directly to the broth, or serve with chili oil or extra sliced chilies on the side.
- Creamier Texture: For an even richer and creamier soup, you can add an extra splash of coconut cream (the thick part from the top of a can of coconut milk) just before serving.

Health Benefits
Tom Kha Gai is not just delicious; it also offers several health benefits thanks to its wonderful ingredients.
Coconut Milk: Full-fat coconut milk provides healthy medium-chain triglycerides (MCTs), which can be easily used for energy by the body. It also contains essential minerals like manganese, copper, and selenium.
Galangal and Lemongrass: These aromatic roots are packed with antioxidants and have anti-inflammatory properties. Galangal is known in traditional medicine for its digestive benefits, while lemongrass may help reduce anxiety and lower cholesterol.
Kaffir Lime Leaves: Beyond their unique citrusy aroma, kaffir lime leaves are a good source of antioxidants. They are often used in traditional remedies for their potential to support digestion and reduce inflammation.
Chicken: Lean chicken breast is an excellent source of high-quality protein, essential for muscle repair and growth. It also provides important B vitamins like niacin and vitamin B6, which are crucial for energy metabolism.
Mushrooms: Mushrooms, especially oyster or straw mushrooms, are low in calories but rich in vitamins and minerals. They offer B vitamins, potassium, and some varieties even provide vitamin D. They also contain immune-boosting compounds.
Serving Suggestions
- Classic Pairing: Serve Tom Kha Gai hot with a side of fluffy jasmine rice to soak up all the delicious broth.
- Main Course: This soup is hearty enough to be a complete meal on its own, especially with plenty of chicken and mushrooms.

Storage Tips
Leftover Tom Kha Gai can be stored in an airtight container in the refrigerator for up to 3-4 days. While it can be frozen, the coconut milk may separate slightly upon thawing and reheating, affecting the texture. If freezing, thaw overnight in the fridge and reheat gently on the stovetop. You might need to stir vigorously or add a splash of fresh coconut milk or water to restore its creamy consistency.
